DEVICE FOR FILLING SELF-FEEDING INK-WELLS.

Application filed November 8, 1906.

To all whom it may concern:

Be it known that l, JOHN MCOLosKEY, a

' citizen of the United States, residing in Boston, in the county of Suffolk and State of connection with the accompanying draw-- ings, is a specification, like letters on the drawings representing like parts.

This invention relates to a device for filling self-feeding liquid receptacles and is especially adapted for filling self-feeding inkwells of that class having a tube attached to the cover for the inkwell and extended down into the same. For this purpose I prefer to employ a valve fitting, which is adapted to fit into the tube attached to the cover and is provided with a fluid inlet which is connected with the ink supply and is provided with a fluid outlet which communicates with the ink well. The valve fitting is provided with means for automatically venting the ink well when the fitting is inserted into the tube in These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 represents in section and elevation an ink we ll provided with-a filling device and a bottle from which the ink is supplied to the well; Fig. 2, a longitudinal section of the 'filling device shown in Fig. 1, Fig. 3', a detail to be referred to, and Fig. 4, a modification to be referred to.

Referring to the drawing, a represents a self-feeding ink well, b the cover therefor having a tube c which depends therefrom into the well a and regulates the amount or depth of ink into which the pen can be inserted, and d a washer to form an air-tight joint between the cover and well.

The present invention has for its object to provide a device by means of which the ink well may be filled with ink from a source of supply, such as the bottle f, without removing the inkwell from the desk in which it is placed, and so that the well may be filled with ink above the bottom of the tube c while preventing the ink from rising in the tube c above the bottom thereof. For this purpose, I prefer to employ a valve fitting la provided with an inlet port or passage i, and with an outlet port or passage j, and with a valve 7c' which controls communication between said ports. The outlet port or pas- Specification of Letters Patent.

sage y' may and preferably will beformed in a stopper m, which may be made of metal and be cast integral with the valve fitting as represented in Figs. 1 and 2, or which may be made of rubber or other suitable material and fitted over a tube n constituting the fluid outlet for the valve fitting as represented in Fig. 4.

When the stopper m is made of metal as represented in Figs. 1 and 2, it may be provided with a sleeve o of rubber or other suitable material, to form an air-tight fit with the tube c when inserted therein as represented in Fig. 1. The valve lc may behand-operated after the manner of the usual needle valve which construction is well known or as is preferred, it may be automatically closed by a spring p located within the fitting a and bearing against a sleeve or collar 10 forming the valve seat and against a head 12 to which the stem 13 of the valve is secured. The head 12 may also have secured to it a stem or rod 15 which extends out of the fitting and is accessible for moving the valve lc from its seat. rllhe 'stopper m is provided with an outlet for the air confined in the inkwell, and the outlet referred to, may be made as hereinshown, so that the compressed air in thewell may be removed therefrom while the ink is flowing into the well, and to such extent that the ink may fill the well above the level of the bottom of the tube c. For this purpose the air outlet is made in the form of a tube 20, which is extended through and movable longitudinally in a passage or opening in the stopper, and said tube is provided with an upturned portion or bend 21 at its lower end and may and preferably will be provided at its upper end beyond or outside of the inkwell with a mouth piece or funnel 23 with which cooperates a valve 24 for a purpose as will be described.

The passage in the stopper through which the air outlet tube is passed, is preferably located eccentrically with relation to the stopper, and the bent lower end or portion 21 of the said tube is made so that the distance from thev outside of the tube to the outside of the bent portion 21 is substantially equal to the diameter of the lower end of the stopper m, whereby the said tube may be readily inserted through the tube c of the cover, when the stopper is fitted into the latter, the air tube being at such time substantially in the position represented in Fig. 2. After the stopper has been fitted into the tube c, the

air outlet tube 2O may be turned vso as to bring its bent portion or leg 21 outside of the tube c, after which said air tube may be moved upward in its passage or opening in the stopper, so as to bring the mouth of the bent portion or leg 21 of the air outlet tube above the bottom of the tube c as represented in Fig. 1, thereby enabling the inkwell to be filled with ink above the level of the bottom of the tube c.

After the well has been filled with ink as described, the supply is cut off by the closing of the valve lc which is effected by the spring i p when the hand-pressure is removed from the stem shown in Fig. 2, or the valve is positively closed by hand with the needle form represented in Fig. 4, and the air tube is then moved downward and turned into substantially the position shown in Fig. 2, after which the stopper is removed from the tube c. y

Provision is made for preventing overflowing of ink through the air outlet tube, which may be accomplished as shown by means of the float valve 24 located in the air tube 20 and adapted to close the mouth of the funnel 23 as represented in Fig. 3. valve 24 may normally rest upon a perforated disk 27 or it may be a wire or projection within the tube 20. I may prefer to use the automatic valve 24, which is closed by the ink when the latter has filled the air tube, as by so doing, the ink is prevented from overflowing onto the desk, in case the operator should fail to close the valve lc at the roper time. Provision is also made for indicating the position of the bent portion or leg 21 of I the air tube, and this may be accomplished byproviding a lug 28 on the funnel 23, which is adapted to strike against the valve fitting when the air tube is in its operative position as represented in Fig. 1. I refer to provide the air tube with the funne 23, as provision is thus made for the ink to rise above the air tube and opportunity is afforded the operator to close the valve k before the ink can overflow the funnel, and the latter also takes care of any ink which might flow out of the air tube before the valve 24 is seated. In Fig. 4, the flow of ink from the inlet pipe i to the outlet tube is controlled by the needle form of valve, which is not shown but is attached to the end of the stem 15 and as it is well known, it is not deemed necessary to show the same.
